SPECIFICATION forming part of Letters Patent No. 499,830, dated June 20,1893.

Application filed February 18, 1893. Serial No. 462,850. (No model.)

- improvement in hoisting coal wagons that are employed for the deliveryof coal to consumers, and for the dumping thereof at the point ofstorage without the usual shoveling of the coal into baskets and otherreceptacles to be carried from the point of dump to storage.

To this end the invention primarily contemplates an improved unloadingwagon, which, while specially adapted for the delivery of coal in smallquantities, at the same time can also be used for other self-dumping andhoisting purposes.

With these and many other objects in view which will readily appear asthe nature of the invention is better understoodthe same consists in thenovel construction, combination and arrangement of parts, hereinaftermore fully described, illustrated and claimed.

In the accompanying drawings:Figure 1 is a perspective view of ahoisting coal Wagon, the body being hoisted to a, dumping position. Fig.2 is a central vertical longitudinal sectional view of the wagon,showing the chute gate open in a position to discharge the coal toeither side of the wagon. Fig. 3 is a horizontal sectional view on theline osm of Fig. 2. Fig. 4 is an enlarged detail view showing one of thesegment guidesl Fig. 5 is a detail in perspective of the bottom of thewagon body showing the lifting arms bearing there- Fig. 6 is a detailplan view of the chute end of the wagon body showing the chute gate openand the extensible chute disposed at an angle to the wagon body todischarge to one side of the same. I

Referring to the accompanying drawings, A represents the bed or truckframe of the ordinary construction, and supported on the front and rearwheels B, in the usual manner.

Secured to opposite rear ends of the truck frame A, are the oppositevertical guide bars or standards O,which are securely braced from theirupper ends to the opposite sides of the truck frame by means of thebrace rods 0. The said opposite rear guide standards G,-receive theopposite guide clips 0, secured to opposite sides of the verticallymovable tilt.-v ing wagon body D, and at the rear dumping end thereof.The said wagonv body D, is of the ordinary construction and is providedwith a sliding end gate d, inclosing'the rear discharge opening, fromwhich leads the short fixed chute d, which forms a contracted outlet ordischarge for the material within the wagon, and said wagon body may bepartitioned off so as to accommodate different quantities of coal to beseparately delivered as will be readily understood. The said movablewagon body D, has secured to opposite bottom edges thereof thelongitudinal metallic roller guide plates E, on which move theant-i-friction-rollers F, at the moving extremi ties of the oppositepairs of crossing front and rear lifting arms G and G, respectively.

The front pair of lifting arms G, are lifted independently of the armsG, so as to provide for lifting the front end of the wagon body beforeand higher than the rear end thereof, and said front pair of liftingarms are pivotally attached at one end as at g, to opposite sides of thetruck or running-gear frame A, near its rear end, while the othershorter rear lifting arms are pivotally attached at g, to opposite sidesof the running gear frame, near the front end thereof. \Vhen the movablewagon body is loaded and rests flat on the running gear or truck frame,the opposite lifting arms fold down within said truck frame as can beclearly seen in the drawings.

The wagon body D, is hoisted into a tilting position by means of theopposite toothed segments or segment-bars II. The opposite toothedsegment bars H, are provided at their upper ends with the notches h,embracing the longer front end lifting arms G, and at the bases of whichare arranged the anti-friction rollers h, contacting with said liftingarms so that, as the Wagon body rises, the said lifting arms are free toslide through the upper notched ends of the lifting segments. The saidlifting segment bars 11, are further provided at a suitable pointintermediate of their ends with the laterally extending lifting pins J,which, after the front end of the wagon body has been lifted a certaindistance, are designed to come in contact with the under edges of therear end-lifting arms so-as to carry up the rear end of the wagon body,as will be easily understood. The opposite toothed lifting segments l-I,work within the curved guide pockets K, of the guide plates 70, securedto oppositeinner sides of the running gear or truck frame A,intermediateof its ends. The curved guide pockets K, correspond to the curvature ofthe lifting segments and carry therein the combined guide andanti-friction rollers L, over which the smooth edges of said segmentsslide, as the same are moved up and down. The segments 1-1, are heldinto the guide pockets K, and are lifted up and down by means of thelifting pinions M, mounted on opposite ends of the transverse liftingshaft m,'journaled in opposite sides of the frame A. The transverselifting shaft m, also carries the cog-wheel m", which meshes with anadjacent pinion N, on one end of the stub shaft n, journaled at one sideof the frame A, and carrying at its outer end the cog-wheel n. Thecogwheel 01., is turned by the adjacent driving pinion O, mounted on acrank handle shaft 0, having an outer squared end adapted to detachablyreceive the operating crank handle employed for operating the wagon. Agravity check pawl P, is pivoted to a suitable point of attachmentadjacent to the cogwheel n, and is designed to hold the hoisted load atany desired point, while adjacent to the driving pinion O, is pivoted apawl brake lever Q,'under the control of the operator so as to ease thedrop of the wagon body onto the truck or running gear frame. Now it willbe readily apparent that when it is desired to hoist the Wagon body, bystarting the train of gearing described from the crank handle, theopposite lifting segments H, are forced up and out of their guides, andtherefore lift the lifting arms G, and the front end of the wagon body.If it is desired to increase the tilt of the body and also lift the rearend thereof, the gearing is merely kept in motion so that the liftingpins of the segments come under the rear end lifting arms and thereforealso carry up the rear end of the wagon body to the desired elevation asis clearly seen in Fig. 1 of the drawings. After the wagon body has beentilted to the desired elevation, it is necessary to provide means forconveying the coal or other material theresliding extensible chute T, isof the ordinary sectional construction, and which, when extended fromunder the wagon body, is designed to form a continuation from thefixedchute d, at the rear discharging end of the body, and said extensiblechute can be turned, when extended, at an angle to the rear end of thebody, and still deliver the material so that the wagon can be drivenalongside of the pavement without the usual backing in.

In order to render the chute T, available for discharging to either sideof the wagon body as clearly shown in detail Fig. 6 of the drawings, theshort fixed discharge chute d, is provided in the bottom thereof with abottom discharge opening X, which is designed to be covered anduncovered by the gate Y, hinged at y, to one edge of said opening. Whendischarging straight to the rear of the wagon body the gate Y is closedas shown in Fig. 2, but to discharge to either side of the wagon bodythe same will be opened, and the chute T, turned around at an angle tothe wagon body on its swiveled eye 3, so that the discharging coal willdrop through the opening X, onto the chute T, and thereby be dischargedto either side of the wagon body without clogging. After the hoistedwagon body is lowered onto the running gear or truck frame,'the saidchute is slid back intov position under the body and is supported at itsouter end by means of the suppo'rtinglink if, placed into engagementwith the hook-end t, of the slide rod R.

From the foregoing, it is thought that the construction, operation andmany advantages of the herein described hoisting coal wagon will bereadily understood, and it will be noted that changes in the form,proportion and the minor details of construction as embraced within thescope of the appended claims, may be resorted to without departing fromthe principle or sacrificing any of the advantages of this invention.
